Investing goals and objectives define this. Cryptocurrency can be invested anywhere. For example, PayPal and SoFi are not solely focused on crypto, but both provide digital assets. Furthermore, if you're looking for low-cost options, you can trade cryptocurrencies using fee-free brokerages such as Webull and Robinhood. In this case, you will not have access to the crypto-specific capabilities offered by Kraken or Gemini.

Of course, I would say definitely if as an investor you prefer it that way. There are other options as you mentioned but I know some prefer to use such exchanges. Just make sure to consider fees.

Using cryptocurrency exchanges can be worth it for traders and investors seeking high returns, 24/7 market access, and decentralized finance opportunities. These platforms offer fast transactions, global accessibility, and exposure to innovative assets like Bitcoin and Ethereum. However, they come with risks such as high volatility, security vulnerabilities (hacks, scams), and regulatory uncertainty.

For active traders, exchanges provide liquidity and advanced tools like margin trading and derivatives. Long-term investors benefit from diversification but must securely store assets in cold wallets to avoid exchange breaches. While lower fees than traditional finance are appealing, users must research platforms thoroughly, opting for reputable, regulated exchanges like Coinbase or Binance.

Ultimately, cryptocurrency exchanges are valuable for tech-savvy users who understand the risks and practice strong security measures.
